Shimano Dura-Ace

DURA-ACE R9100 series

ULTIMATE CREATION IN SYSTEM ENGINEERING

The DURA-ACE groupset is the result of Shimano’s ongoing passion for technology. This is reflected in every single component in the groupset. All components are joined together to work as one, reinforcing each other for unparalleled performance. This is how DURA-ACE achieves ultimate supremacy.

System engineering at its peak. Each of the components magnifies the qualities of the others for an unparalleled level of performance. Optimizing input to maximize output. That's how it achieves supremacy.

Optimal power transfer

Rider-tuned gearing options

Iconic design

The R9100 series crankset achieves the ultimate in optimal power transfer. It does this through its broader Hollowtech II arm and a more reinforced outer chainring on its unique asymmetrical four-arm spider construction. The new R9100 cranks set the highest standards for stiffness and lightness

State of the art Di2 electronic technology for instant, accurate shifts first time, every time, at the push of a button. Now 11-speed compatible, with enhanced feedback and improved ergonomics for easier access to the shift buttons from the top of the the hoods. Cleaner wiring thanks to single-wire E-tube connections, that also make it easy to add satellite shifters for bar tops or in the drops.

Dura-Ace moves to the next generation. Reduced shifting effort lets you concentrate on riding. More control thanks to improved ergonomics. Unbeatable reliability gives you confidence. Tested in competition and taken to victory by pro riders in all conditions - on the road, across the pavé, through the mud. Dura-Ace: Concentration, control and confidence.

Rider-tuned means Dura-Ace works the way you want it. The new 11-speed cassettes are available in a range of sizes including a wide-range 11-28 option - one cassette to use all year round. Smooth, fast shifting guaranteed.

The 11-speed Dura-Ace rear derailleur has been redesigned for lighter operation with the help of new low-friction polymer-coated cables. Shifting effort is now more even across the range, with similar force required at both ends of the cassette.

The new Dura Ace 11-speed chain is no longer directional, has hollow rivets for a low weight and a PTFE coating for soft switching operations. The CN-9000 is also characterized by a higher durability compared to the CN-7900.
